Ariane 64 Block 2 | Amazon Leo (LE-04)
Pad: Ariane Launch Area 4 · Guiana Space Centre, French Guiana
Amazon Leo, formerly known as Project Kuiper, is a mega constellation of satellites in Low Earth Orbit that will offer broadband internet access, this constellation will be managed by Kuiper Systems LLC, a subsidiary of Amazon. This constellation is planned to be composed of 3,276 satellites. The satellites are projected to be placed in 98 orbital planes in three orbital layers, one at 590 km, 610 km and 630 km altitude. 35-40 satellites will be carried on each Ariane 6 launch.

The Earth's maximum rotational surface velocity (~1,670 km/h) gives rockets launched here a free velocity boost, making it the most energy-efficient spaceport on Earth for geostationary (GTO) and interplanetary insertions.
